IMPROVEMENT in DUMPING-SLED.

.TO ALL WHOM IT MAY CONCERN:

Be'it known that I, E. R WHl'fr ti g-jof Plattsburg, in the eounty ofClinton, and in the State of New York, have invented-certain new anduseful Improvements in Dumping-Sleds; and do hereby declare that thefollowing is afull, clear, andexact description thereof, reference beinghad to the accompanying drawings, and the letters of reference markedthereon. In the annexed drawings making a part of this specification- IA represents an ordinary sled, of any suitable size, provided withverticalgposts 0 extending up a suitable distance from about the middleof the opposite sides of the sled A.

The posts C are provided with slots or holes, in which are secured andwork pulleys k, as shown in the drawings. I r

On the top of the sled A, and between the stay-rails or ravesthereof,.are adjusted movable bars B, whichmove in suitable ways on thecross-bars of the sled and loops g on the inside of the sled-runners.The bars B are framed together at their forward end by means of asuitable cross-bar, to which power to draw the sled A is attached. Saidbars are held iii place, and from being drawn out, by mea'nsof'a simplecatch-hook, K, attached to the forward cross-bar of the sled, andhookingdnto a staple in the cross-piece. of the bars B. Adjusted andsecured to thehind or back cross-bar of the sled A are pulleys j. v

D represents a box or body of suitable dimensions to fit and workbetween the vertical posts 0 pivoted to or on the back part of the sledA in any convenient manner, and having a cross-slat secured to its underside in front of the postsC, to which one end of the cord f is fastened.The body D has also in front a suitable loop or staple, which fits andworks over the guide or standard E. Said standard E is pivoted to themiddle of the forward cross-bar of the sled A, and jserves asa guide forthe'front end of the body D when the same is tipped up or elevated, Hrepresents a spring-catcher brake, which is operated by the foot for thepurpose of stopping and holding the sled Afro-m-slipping forward whiledumping.

A cord, F, is secured to the rear end of the sliding bars 13, and-passes thence around the pulleys j and up over the pulleys 7t, and thenfastened to the ends of the cross-slat of the body D, as is fully shown.By detaching the hook K, and pressing down on the brake orcatch H, thebars 13 may be drawn forward by the team attached thereto, and the cordsF working over the pulleysj and h elevate the front end of the body I),and the load therein is thereby dumped or thrown out. The convenience,simplicity, and economy of this device will he readily seen.

Having thus fully described my invention, what I claim as new, anddesire to secure by Letters Patent, is-

1. The sliding bars B, when used in combination with a cord, F, for thepurpose of elevating the front part of a body, D, of a sled or wagon,and operated as and for the purpose specified. I

2. Operating a dumping-body, D, by means of the same team which drawsthe same, without detaching and reattaching said team, substantially asand for the purpose specified. I

3. The arrangement of the posts 0, pulleys h and j, with thecords F,when operated by means of sliding bars B, as and for the purpose hereinset forth.

In testimony that I claim the foregoing, I have hereunto set my hand,this 28th day of January, 1868.
